About The Position

The Senior Photolithography Equipment Technician maintains, troubleshoots, repairs, and performs preventive maintenance on photolithography equipment in a semiconductor wafer-fabrication cleanroom. The role includes maintaining equipment records and work orders, providing shift pass-downs, coordinating with Production and Process Engineering to prioritize equipment issues, and supporting inspections, SPC, quality control, process monitoring, metrology, and equipment-improvement projects. The position also supports semi-automated and automated wafer-processing systems and follows applicable workflows, data-entry requirements, cleanroom practices, ESD controls, and site quality and environmental requirements. This is a full-time, on-site position. The posting describes a 12-hour night shift from 5:00 PM to 5:00 AM and also notes that two positions are available, for day and night shifts. Schedules described include a rotating three-day/four-day schedule with every other Saturday, and a day-shift schedule from 5:00 AM to 5:00 PM Sunday through Tuesday and every other Wednesday. The role requires at least 10 years of semiconductor wafer-fab experience and extensive experience maintaining photolithography equipment. The technician must be able to work independently and as part of a fast-paced team, respond to production priorities, communicate clearly, follow procedures meticulously, and work in a cleanroom while wearing required garments and PPE. Physical demands include extended standing and walking, handling small parts and precision equipment, bending, reaching, kneeling, working in restricted-access areas, and lifting up to 50 pounds. Employees must follow site EHS procedures and Coherent Corp. Corporate EHS standards. Depending on location, the position may be responsible for executing and maintaining applicable quality and environmental management system standards, including ISO 9000, ISO 9001, and ISO 14001.
